We have shown our invention embodied in en n. peretus combined with :tcooler of the cellu er type,isuch as is shown in our applica.- tion for,Letters Potent, Serial N umbcr Patent Ollice.

A, is the fon shaft. A, is c pulley on scid shaft, und A is the fon forectuctiinlr a current of air through and post the cooler.

E, E, is the cooler, and C, C, ore the cells or tubes of which thecooling surface is mede up.

B, is e centrifugal pum r built into the cooler in the center thereo andhaving its center exielly in line oith that of the fen A. Tubes ereremoved from the cooler to form o central opening to receive thc pumpand the pump is put into this opening to lill the seine rind soldered inplace lo forni on integral port of the cooler.

B, is the forward plate, sind B1, is the reer plate of the pum B theseplates forni art of Vthe correspon ing surfoccs of thc coo er.

l, is a. partition extending7 transversely dividing, said pump into tvochambers B,

degrees. Bl, in the (honing denotes this opcnnig. 'the chfunbcr B* isopen :it the bottoni l'oi about one hundred und eighty degrcco nsindiculcd al l 'lhe shaft of the f lon A extends l'oiw ord through estul'lingr bor; or lhind through the chamber B um into thc cluuubcr lll,und hns oltuehed to it nl this plnrc :t lun Bl.

l), is c partition' extending in cach direction from the pump l, anddividing the oooh-r into en upper :md lower portion communiculiug withmich other only through the pump. The partition is oll S form in crosssection, the two ports licingjv indicated by D und D2 in Fig. 3. 'illusu trough l)l is l'ormcd which receives the lluid desee` dini" frombetween thccooling,` tubes above scid perl-ithin, and leeds it into thechercher B of the pump l5, from which it pesscsthrough thc uperture binto the chamber B, and is discharged from the open lower portion ofsaid chamber into the lower portion of the cooler E.

e1, is the outlet from the cooler to the circuloting system, and e isthe inlet from seid system to the cooler.

The operation of the abonev described device is es follows r-The fan andfen she/ft is operated by a belt in the usuel manner. The rotation ofthe shaft A with the fen A cerrics with it the ump blades B5 which actsto force outward y cent-rihigel torce the Huid in the chamber B, endsucks the fluid through the aperture b3 from the chamber` B3; thusthcfluid returned to the top of the cooler is drawn downward past thecooling surfaces of the pper portion of the cooler, und dischargeddownward pest seid surfaces in the lower portion of the cooler andvforced outward through the outlet pass-ege into the circulating system,which system is of the ordinary construction, except that it is notnecessary to have any Ai'iexible connections. The circulating systembeyond the cooler is well known und therefore is not specially shown ordescribed. lt willbouoticcd that by this orrrmgcmcnt, splice muy beconsiderebly economizcd und fewer moving ports are necessary, while usimple und cllicicnt circulating and cooling system is provided, inwhich the lluid is properlydistributed through the various passages ofthe cooler.
